Using Version 6.002 w ith Earlier Firmware Revisions
Tests with version 6.002 firnware show the network polling time of a typical
DeviceNet network is approximately twice as fast when compared to the same
test run with earlier versions of the 1756-dnB firmware. You must consider
this significantly faster polling time when duplicating applications designed
for earlier firmwate revisions

If your system control is programmed or dependant on specific DNB
performance, then you can increase the Interscan Delay(ISD)in the V6.002
1756-DNB scanner to add a delay to the polled network scan. This will allow
the network scan time of V6.002 1756-DNB to more closely approximate that
of the V5.002 module for system timing purposes

DeviceNet auto scan
By using Auto Scan, you can easily create a scan list without having to use
RSNet Worx for Device Net. Starting with major revision 4 of the 1756-dnB
DeviceNet scanner, you could initiate an AutoScan of a DeviceNet network
programmatically in your application
With rslogix 5000 v13 and major revision 5 of the 1756-DNB DeviceNet
scanner, you can initiate an AutoScan operation from the scanner properties
dialog box in rslogix 5000. When initiating an AutoScan opcration, thc
DeviceNet scanner scans the network and acquires all devices whose transmit
and receive sizes fit into the predefined

Each device is assigned a configurable number of bytes for the I/o data in

To initiate an Auto Scan operation, access the tab called Scan List' that is
available on the deviceNet scanner properties dialog box in RSlogix 5000

Embedded EDS Support
Prior to the release of rsnet Worx version 5, you had to manually install
Electronic Data Sheet(EDS) files for new modules and for new firmware
revisions of existing modules. If you did not install the new EDs file, RSLinx

The 1756-DNB v5.002 module now includes the current EDs file as part of

While browsing the device Net network in rsNet Worx v 5. node #1 shows
up as an Unrecognized Device. You know that Node #1 is in fact a
